   STEMX — Bauhaus block layer

   Loaded after style.css and fx.css. Everything here is the geometric
   vocabulary the base sheet does not have: square / circle / quarter-round
   ornaments, hard block strips, and the purple accents that mark structure.

   Rule of the palette: black and white do the reading, purple does the
   pointing. Purple never carries body copy — only edges, markers and hovers.
